Here, we compare the lineal-path functions for the void phases of the three classes of Debye random media in 2D. Following Lu and Torquato [1]}, [2]}, one will find that \(L(z)\)  for overlapping polydisperse disks is
\(L(z) = \phi _1\exp \left( \ln \phi _1 \frac{2\langle R \rangle }{\pi \langle R^2 \rangle } z \right).\)
